.TH MKFS 8 "2 July 1996" "Util-linux 2.6" "Linux System Administrator's Manual"
.SH NAME
mkfs \- make a Linux MINIX filesystem
.SH SYNOPSIS
.BR "mkfs [ \-c | \-l filename ] [ \-n"
namelength
.B ] [ \-i
inodecount
.B ] [ \-v ]
device
.B [
size-in-blocks
.B ]
.SH DESCRIPTION
.B mkfs
creates a Linux MINIX file-system on a device (usually a disk partition).
The
.I device
is usually of the following form:
.nf
.RS
/dev/hda[1-8] (IDE disk 1)
/dev/hdb[1-8] (IDE disk 2)
/dev/sda[1-8] (SCSI disk 1)
/dev/sdb[1-8] (SCSI disk 2)
.RE
.fi
The
.I size-in-blocks
parameter is the desired size of the file system, in blocks. This
information can be determined from the
.BR fdisk (8)
or
.BR cfdisk (8)
program. If omitted it will be determined automaticaly. Only block
counts strictly greater than 10 and strictly less than 65536 are
allowed.
.SH OPTIONS
.TP
.B \-c
Check the device for bad blocks before creating the file system. If any
are found, the count is printed.
.TP
.BI \-n " namelength"
Specify the maximum length of filenames. No space is allowed between the
.B \-n
and the
.IR namelength. Currently, the only allowable
values are 14 and 30.
.B 30 is the default.
.TP
.BI \-i " inodecount"
Specify the number of inodes for the filesystem.
.TP
.BI \-l " filename"
Read the bad blocks list from
.IR filename .
The file has one bad block number per line. The count of bad blocks read
is printed.
.TP
.B \-v
Make a Minix version 2 filesystem.
.SH "EXIT CODES"
The exit code returned by
.B mkfs.minix
is one of the following:
.IP 0
No errors
.IP 8
Operational error
.IP 16
Usage or syntax error
.SH "SEE ALSO"
.BR fsck (8),
.BR mkefs (8),
